• High maximum discharge current capacity (Imax) of 50 kA • State-of-the-art thermal disconnector • Leakage current-free technology • Backup fuse up to 315 A gG • Short-circuit current rating up to 50 kA • Vibration and shock withstand capability • VDE-IEC Class II / EN Type 2 certified • All modules including N-PE, with operating state green-red • Optional remote contact signaling (RC) The ProTec T2H surge protection device provides high durability due to its leakage-free performance ensured by a special series connection of varistor and gas discharge tube. The ProTec T2H product family is an ideal supplement to the basic ProTec T2 product family, available for single or three-phase TN-S, TT, and TN-C systems with a maximum continuous voltage of 300 V AC. The perfect solution for applications such as railway safety control systems where the complete absence of leakage current, is required. With its Type 2 classification, the unit can be installed between boundaries 1 – 2 and higher. The varistor based protection module features outstanding short-circuit currents up to 50 kARMS without using a back-up to the main fuse and a nominal current of 315 A. All modules are equipped with a state-of-the-art thermal disconnector and life-status green-red monitoring indicator. A unique vibration-proof locking mechanism enables secure use in high vibration environments. An optional remote contact (RC) features a three-pole remote signaling terminal, which enables remote monitoring of the operating state of the device.
